To all whom it may concern:

Be it known that I, PAUL BROWN KLUGH, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in Bellows-Chests, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to bellows chests for pneumatically operated piano layers.

The object of the invention 1s to provide economical' and eiiicient mechanism of this character, readily fitted and attached within the case of an ordinary piano of standard sizeand as readily removed therefrom, adapted-to be attached or removed in separate sections in building, repairing or gaining access to parts normally concealed by the' chest, without necessitating the removal or disturbance ofthe entire bellows chest and having capacity for maintaining sub- .fstantially uniform tension throughout the severa-l sections.

In general, the invention contemplates the construction of a bellows chest comprising a plurality 'of sections each separately attached 'and removable or. detachable one from` the other, two corresponding sections being operated by the usual bellows or tension creating mechanism, and means for removably vsecuring the sections in pneumatic .intercommunication within a piano below the keys.

In the accompanying drawings I have shown a device embodying my invention in vits preferred form.

Fi re l is avfront view of a piano show ing t e device in attached position below the key-bed, andFig. 2 is an enlar ed broken cross-section n line 2 of Fig. l, illustrating my preferred methodbf attaching the secl tions within the piano the pumps and reservoirs omitted.

In the drawings, I have shown abellows chest composed of two sections ay a, butl it is obvious that any plurality may be used, where desired. Two corresponding sections are. each provided with the usual pumping bellowsV 8 8*, expansible reservoirs 10 10, pedal mechanism, ports and valves for main-1 taining.' neumatic'tension within the sections. ese'tension-creating,devices being weil known in the art, need not be, further i described. The sectional construction fof the,

bellows chest enables the builder toseparately distribute the several sections makes it possible to tit the. Chest into piano cases of different widths and facilitates-Mn tachment anddetachment. In orderto gainv secure the outer ends of the right and llfj;

hand sections, or those adjacent to the "inside of the end walls of the piano, I prefer to secure a pair of upright cleats 5 and 5 on the left hand endand 6 and 6a onthe right hand end, both pairs ta' ering inwardly so as to form the opposite y disposed recesses or sockets. Cleats on the'same side of the case of the piano are far enough apart to permit the outer ends of the exhaust device to lit snugly between them. Adjacent ends of sections I prefer to secure or interlock by providing upright supports '1, havin two vertically disposed straps countersu andbent over the top at right angles, so that they may be screwed, or otherwise removably secured, to the piano, either to the key.- bed or to the lower end of the string frame Q.

Rigidly secured to each upright 1, or made integral with it, is a vertical wedge block or tongue 4, .tapering outwardly and of sufficient size to fill the intervening space he- The end sections are secured within.

The relative size of the parts is such that the tapering sides of wedge 4 when used between the adjacentids of sections crowd and hold them together, in which lposition the may be detachably fastened by suitable bo ts and /nuts' 8 and 3a passingthrough upright 1'.l

- VIn order that the pneumatic tension may 'be the same within the sections, I cut an vopening in each and't the end of adetaoh-l able and vflexible pipe or other wind-way connection thereto, indicated in the drawings by 12. -The configuration of the .ends

Q emessi tions 'will suggest themselves to those skilled@` in thearttand I do not wish to be ilcldei"l stood aslimiting myself to the device dei scribed andshown; but

What I claim is. v

1. In a piano player, in combination with aiano having sockets disposed on opposite Si,

es thereof Abeneath the keys,V va bellows chest composed of a plurality of sections9 the ends of said sections adjacent to said sockets being adapted to tv therein, and 4Vertical Wedge blocks adapted to t between adjacent inner ends of said sections, whereby said sections are separately removably secured lwithin'the piano.

' 2. In a piano playerin combination with a iano having sockets disposed on opposite si les thereof beneath the keys thereof, a bellows-chest, the ends thereof adj aent to said sockets being adapted to fit therein, whereby said chest' is removably secured within the piano. 3. 'l`he combination of bellows chest sections,A oppositely disposed sockets secured on the sides of the interior of a piano below the keys and wedge tongues adapted to be inserted ybetween the inner ends of said sections to force said outer ends into said sockets, whereby said sections are locked to the piano, substantially as described. 4. The combination of the bellows chest sections a; a', a pipe connecting them, oppolsitelykdisposed sockets adapted to be secured on the. si'des of a piano, and a wedge member adapted to hold the ends of said sections 40 in said sockets and' to be locked to the piano, substantially as described.

In testimony whereof I hereunto ax my signature-in the presence of two witnesses. PAUL BROWN KLUGII. Witnesses:
